0202	New variable stars in the fields of AP And and SW Lac 2228 kB	Gaynullina E.R., Khalikova A.V., Serebryanskiy A.V., Karimov R.G., Burkhonov O.A.	2019-10-19
	New eclipsing binary star (USNO-B1.0 1357-0539679 = UCAC4679-131592 = 2MASS23494870+4543155) was discovered in the field of AP And. Taking into account the shape of the light curve, its period of P=0.3406908(27) day, amplitude of $R\approx$0.18 mag, we classify this star as the eclipsing binary system of W UMa (EW) type. Four stars in the filed of SW Lac also show variability. TYC3215-1288-1 = USNO-B1.0 1280-0618346 and TYC3215-1406-1 = USNO-B1.0 1278-0636029 might be irregular variable stars, USNO-B1.0 1280-0618262 = 2MASS 22533785+3802543 might be quasi-regular variable star with rotation modulation and with the period of P=12.73(4) days, and TYC3215-906-1 = USNO-B1.0 1279-0627071 is suspected to be the binary star with the period of P=1.0939(12) day. Objekty Simbad: TYC3215-1406-1, TYC3215-906-1, USNO-B1.0 1280-0618262, TYC3215-1288-1, USNO-B1.0 1357-0539679,		komentáře: 0
